fiOOK-AND- EYE TAPE.

Application filed February 23, 1927. Serial No. 170,246.

My invention relates to hook and eye tapes in which a strip of woven fabric is folded on itself to form protecting and re-inforcing flaps through which the hooks and eyes pass and in which the hooks and eyes themselves serve to hold the various plies in position without sewing and which plies cover and conceal the bases of the hooks and eyes and it is my object to produce such hook and eye tape cheaply, quickly and in quantity by the use of automatic machinery which will fold the fabric, form the hooks or eyes insert them in the folded fabric strips and produce the finished article without sewing, stitching or riveting which will have a smooth, unbroken back with no metal exposed and which lies absolutely fiat without curve or wrinkle such as is present in the ordinary sewed hook and eye tape.

In the drawing Fig. 1 is a face view of the hook tape; Fig. 2 a face View of the eye tape, Fig. 3 a sectional view of the structure of Fig. 1 on the line 8-3 thereof; Fig. 4 a sectional view of the structure of Fig. 2 on the line 44 thereof; Fig. 5 a sectional view of a modified form of the tape; Fig. 6 a view of'a hook ready for insertion in the folded tape; and Fig. 7 a view of an eye ready for insertion in the folded tape.

The tape comprises a strip of woven fabric which is folded over to form the outer faces 1 and 2. The ply 1 is then folded in at its free edge to form the ply 3 and the free edge is then folded back to form the ply 4.

The ply 2 is folded at its free edge to form the ply 5 and then back on itself to form the ply 6. The plies 5 and 6 lie between the plies 3 and i with the ply 4 between the plies 2 and 5.

The hooks 7 or eyes 8 are formed with open bases 9 or 10 as shown in Figs. 6 and 7 are then inserted through the ply 1, the fold line between the plies 3 and 4 and the fold line between the plies 5 and 6 after which the base loops of the hooks or eyes are formed, after which the plies 3 and 6, to-' 'ether with a portion of the ply 1 is laid down over the bases of the hooks or eyes. By this construction the pull or strain on the hooks and eyes comes on the folds between the plies 3 and 4 and the folds between the plies 5 and 6 so that any tearing strain is resisted by two full thicknesses of fabric and the bases of the hooks and eyes are completely covered, concealed and rotected by the fabric strip. In addition t e front and back of the tape present a smooth, unbroken fabric surface and there are no raw edges exposed as folds occur at the edges of the. finished tape and all raw edges are turned on inside the tape. Another great advantage resulting from this method of using the hooks or eyes to hold the various plies of fabric together lies in the fact that the finished tape lies absolutely flat and can be more quickly and accurately sewed to a garment than a sewed tape can because a sewed tape is more or less curved or wrinkled due to the pull of the stitching passing through the various plies.

In Fig. 5 I have shown a modification made of two strips of fabric. The wide strip is folded on itself to form the plies 20 and 21 which have the raw edges turned in at 22 and 23 to present a. finished edge. The second, narrower strip is folded on itself to form the plies 24; and 25 and the unformed. bases of the hooks or eyes are pushed through the ply 20 and the fold between the plies 24 and 25 after which the base loops are formed. In this way the two strips of fabric are secured together without stitching and when the tape is sewed to a garment as indicated by the stitch lines 26 and 27 the pull on the hooks and eyes comes on the fold between the plies 24. and 25 and the stlitching 26 which passes through all the p 1es.

By this construction the hook and eye tape is produced at high speed on automatic machines which fold the fabric, manufacture the hooks or eyes from wire, insert them in the plies, form the bases and lay thecovering Y folds over the bases.

1 claim 1. A tape for hook and eye tape comprising a strip of woven fabric folded on itself to form the first and second plies. the free edge of the first ply being folded inwardly to form the third ply and then outwardly to form the fourth ply, the free edge of the second ply being folded inwardly to 'form the fifth ply and then outwardly to form the sixth ply, the fifth and sixth plies lying between the third and fourth plies.

2. A hook and eye tape comprising astrip of woven fabric folded on itself to form the first and second plies, the free edge of the first ply being folded inwardly to form the third ply and then outwardly to form the 110 fourth ply, the free edge of the second ply being folded. inwardly to form the fifth ply and then outwardly to form the sixth ply, and sixth plies with the base lying within the fifth and sixth plies lying between the said plies and the engaging portion exposed third and fourth plies and a fastening inemon the face of the first ply. 1 her comprising an engaging portion and a In testimony whereof I have afiixed my 5 base portion extending through the first ply signature.

and through the fold between the third and fourth plies and the fold between the fifth DAVID SILBERMAN.
